Lenin's ideas of people's democratic revolution and its outgrowth into socialist revolution, of an uneven world socialist revolution, of the struggle against imperialist war, of Soviet power as the standard-bearer of democracy, of national equality, of peace and socialism - have nourished the tactics of the world communist movement to this day. Their significance is immortal. At the same time, Lenin himself constantly emphasized that the main thing in Marxist doctrine is materialist dialectics, which requires the analysis of the objective and subjective conditions of the revolution in its development, in concrete connection with changing domestic and international conditions. “...The basic position of Marxist dialectics is that all boundaries in nature and society are contingent and mobile, that there is not a single phenomenon which, under certain conditions, could not turn into its opposite. ”This also applies to the boundary between democratic and socialist forms of class struggle, between stages and varieties of revolution, between internal and international contradictions, between reforms and revolution, explosive and staggered (“peaceful”) forms of the revolutionary process.
